Does anyone have an S4 wiring diagram with the older regulator, the RB.106/2. The shop manual features the newer RB.340 and I'm not certain how to translate between the two. I've got the dash out and want to understand the wiring better before I install the new dash. Thx

Use the S3 diagram in the manual, it shows the RB106 and is otherwise the same as the S4 as far as I can see.

I considered that but I believe the color coding is different?

In which area ?
Apart from the additional components on the S4 the two diagrams look identical to me. The terminals on the RB340 control box do have different identification letters from the RB106 but the wiring colours are the same on both.

OK, will look more closely with that in mind, thx
